The new upgrades are available for Symons and Nordberg cone crushers, and Superior gyratory crushers. They are offered in packages that are easy to take into use; every kit includes clear installation instructions, or alternatively Metso can provide the customer with a field service team for support or for the complete installation.

Jaakko Huhtapelto, sales development director for Metso's Spare Parts, said: “Metso understands the tough nature of the current mining market for our customers, so we made it our goal to design a new generation of crusher upgrades that would enable them to generate more ROI [return on investment] without the need for expensive capital investments. The close collaboration with our customers allowed us to develop these great products that not only will help them to bolster their bottom line, but also lead to a safer job site.”

The new generation of upgrades can be fitted to several of Metso's heritage branded crusher models. The complete range has been specifically designed for the mining market and includes:

Symons cone crushers:

• Advanced bowl adjustment control;
• Hydraulic motor bowl adjustment system; and
• Hydraulic tramp release and clearing system.

Nordberg HP800 and MP cone crushers:

• Jack screw locking nut;
• Top mount clamp cylinder;
• Heavy duty head;
• MP1250 retrofit kit; and
• Head maintenance stand.

Superior gyratory crushers:

• Super spider;
• Arched spider;
• Shimmed spider bushing;
• Hydraulic shell separators; and
• Dual balance cylinder.

For users that implement the upgrades, Metso stated that productivity can be improved through increased product rate capability, easier setting adjustments, better crusher reliability and reduced bridging from oversized materials. Maintenance can be reduced through the improved lifetime of components, more reliable crushing and easier maintenance procedures. In addition, safety can be heightened through better maintenance practices, reduced stoppages from bridging, and the usage of automatic or remote settings.

These upgrades can help customers to get more out of their existing crushers at a cost that is lower than purchasing a new machine.
